Hypalon Washers

Advanced Seals & Gaskets Ltd work with a host of manufacturers allowing us to produce washers from a variety of materials including Hypalon rubber. Our washers are produced on-site using drawings, samples or measurements provided by our customers, with whom we work closely to ensure the final product is to their exact specification. 

Depending upon the size and quantity of washers required, one of many presses, kiss-cut machines or CNC machines can be used to manufacture the final product, from one-off samples to multiple batches runs. Washers are a popular product as many industries require them for sealing against dust, air and moisture, gap-filling between uneven surfaces or for reducing unwanted noise and vibration.  

Our Hypalon rubber washers can be supplied plain or with a choice of finishes including foils, self-adhesives or laminated to other materials, depending on the size and quantity of the gasket, they can be supplied as loosely packed parts or kiss-cut on rolls.

What are Hypalon Rubber Washers?

Hypalon rubber is a high-quality synthetic material also referred to as chlorosulfonated polyethylene, produced by combining and reacting polyethylene with chlorine and sulfur dioxide, this reaction changes the thermoplastic polyethylene into a synthetic elastomer which can then be compounded and vulcanised to produce the finished material. 

When cut into a ring with an outer diameter (OD) and inner diameter (ID) measurement, they form a washer. Hypalon washers can be placed between two surfaces creating a level surface, acting as a spacer/ seal or between a nut/bolt to spread the pressure when tightened.

    Why use Hypalon Rubber Washers?

    Washers are a flat, circular-shaped piece of material with a hole in the centre, usually used alongside threaded bolts, screws and other fasteners. Washers are often used as a type of seal, where they can create air/liquid-tight seals in pipework, but surprisingly serve a number of purposes which include load distribution, to reduce the stress on the materials into which fasteners are driven and therefore reducing damage. 

    Washers are also used as spacers to allow a better fit of fasteners, for example where the fastener is too long, washers can be used to create padding and fill the gap ensuring the fastener doesn't go too deep.  Finally, washers can be designed to absorb vibration, especially when used to connect objects with hard surfaces and a lot of movement.

    Hypalon rubber washers have excellent resistance to ozone, weathering and acids, with exceptional resistance to chemicals and oils and very high or low temperatures, an operating temperature range of -30℃ to +140℃ and high tensile strength. By combining the two compounds in the material manufacturing process, Hyplon demonstrates the moisture resistance, good dielectric strength and chemically inertness of standard polyethene, with the oil and self-extinguishing fire resistance properties produced with the addition of chlorine.

    Advantages of Using Hypalon Rubber Washers

    Using Hypalon rubber to manufacture washers offers a number of excellent qualities which include its chemical inertness, resistance to ozone, weathering and oils, wide operating temperature range, good dielectric strength and self-extinguishing properties. Hypalon rubber is usually manufactured in continuous rolls which can later be cut and converted into washers however being a solid rubber it can also be moulded into o-rings.

    Benefits of Using Hypalon Washers

    • Excellent ozone and weather  resistance
    • Resistance to aggressive chemicals, abrasion and mechanical impact or friction
    • Good resistance to oil and solvents
    • Wide working temperature range
    • Electrical insulation properties
    • Low flammability
